To all whom it may concern..-

Be it known that I, Ennns'r L. Sons, a citizen of the United States, residing at Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Marine Vessels,

following is a specification.

This invention relates to marine vessels, more particularly to the providing of the hull or frame of the vessel with means to prevent the sinking thereof, and has for its object to provide a vessel, in a manner as hereinafter set forth, with sustaining elements, consisting of independent air containing receptacles, disposed throughout the frame and floors of the decks to arrest the submerging or sinking of the vessel when the hull of the latter is damaged or stove in. Further objects of the invention are to provide a marine vessel with sustaining elements simple in construction and arrangement, strong, durable, eliicient in use, conveniently positioned or arranged with respect to the hull and floors of the decks and comparatively inexpensive when used.

\Vith the foregoing and other objects in view the invention consi ts of the novel construction, combination and arrangement 0 parts, as hereinafter more specifically described and illustrated in the accompanying drawing, wherein of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawing wherein like reference characters denote corresponding parts throughout the several views z- Figure l is an elevation, broken away, of a vessel showing the adaptation thereto of sustaining elements in accordance with this invention.

Fig. 2 is a perspective view of a sustaining element.

Fig. 3 is a cross sectional View thereof.

Referring to the drawings in detail 1 de notes the keel. and 2 the bow of a vessel. The bow 2, sides and stern (latter. not shown) of the hull of the vessel are formed from an inner and outer frame. This is clearly shown with respect to the sides and outer frame and is indicated at 3 and the [inner frame at 4. As illustrated the vessel is shown as provided with four lower decks is shown an embodiment S and the floor of each of said of an upper section 9, and a 10 and the said sections 9, 10,

other. The lower secof the decks 5, 6, and the decks 6, 7 and 8.

5, (3, 7 and decks consists lower section are spaced from each tions lOof the floors 7 provide the top of The decks are divided by one or more ver tical partitions, only one being shown, and which consists of spaced sections, 11 and 12. The partitions also provide means for bracing the decks and when one is employed, which is arranged centrally of the hull, it extends to and is supported by the keel 1, as well as depending below the section 10 of the floor of the lowermost deck 8.

The sustaining elements which. are used to prevent submerging or sinking of the hull are arranged between the frames forming the hull, between the sections of the floors of the decks and between the sections of the partition or partitions.

The sustaining elements are referred to. generally by the reference character 13 and are arranged in longitudinal extending rows between the frames of the hull, the sections of the deck floors and thesections of the partition or partitions. The rows of sustaining elements positioned between the frames of the hull extend from the keel 1 to the top of the hull, the rows of sustaining elements arranged between the sections of the deck extend from the bow to the stern of the vessel and the rows of sustaining elements positioned between the sections of the partition or partitions extend from the bow to the stern of the vessel.

The sustaining elements which are positioned between the frames of the hull are arranged at an angle wit respect to the sustaining elements arranged between the floors of the decks and the sustaining elements positioned between tion or partitions are disposed at right angles with respect to the sustaining elementsthe sections-of the parti- Y conform to the curvature of said frames but even when conforming to such curvature are disposed at an angle ,with respect to the sustaining elements arranged between the sections of the floors of thexlecks. v

- Each of the sustaining elements consists of an oval-shaped 1 closed metallic casing 14 embodying a pair t side walls 15,16, a bottom wall'17, a top wall 18 and. a pair of end walls 19. The top wall 18 of each otz-the casings has a longitudinal extending and centrally disposed depressed portion20 provided. with an inlet checkavalve 21 which .casingm. v

Associated with each row of sustaining.

opens into the chamber 22 formed by the elements is an air supply pipe 24;, disposed longitudinally, and communicating with the check valves 21 of the sustaining elements forming the row. The supply pipe 24: is

either connected to a feed pipe (not shown) A and which communicates with-.anyair-comprevent the discharge of air. but will allow the supply to a casing when desired.-

By providing. the rows of independent sustaining elements one may become damaged and which would not interfere with the other row;

What I claim' is:

- "*-.1.' A marine vessel comprising a hull ineluding an inner and outer frame and further having a deck floor formed of an upper and lower section, .a series of independent rows of air containing casings interposed between said frames, a series of independent rows of air containing casings mterposedbetween said floor sections, each of said casings having one wall depressed to provide a longitudinally extending groove, an

' inlet. ,Valyular device mounted in the bottom of'each of said' grooves, and a series of in dependent air supply pipes, each of said pipes common to a row of casings, p0sitioned in the grooves of and connected to the valvular device of'the casings of the row.

2. A marine vessel comprising a hull in,- cluding an inner and outer frame and further having a deck floor formed of an uppfir and loyver section, a series of independent rows of a1r contammg ,casmgs interposed. 1

between said frames, and a series of independent rows of air containing casings interposed between said floor sections, each of said casings being oblong in plan and oval in cross section and each having one wall depressed to'provide a longitudinal groove, an inlet valvular device in the bottom of each groove, and a series of independent air supply pipes, each of said pipes common to a row of c'as-k ings, positioned in the grooves of and connected to the valvular device of the casings of the row.

In testimony whereof I aflix my signature in the presence of two witnesses;
